From Bearing Arms:

According to Dobbins, “The highlighted portion that was shared was under the section of the Online Banking User Agreement as it pertains to person to person payments.”  She added, “Georgia United Credit Union offers its members a convenient person-to-person payment service, allowing for digital transactions using a phone number or email.”

Basically, this is something like Zelle or Venmo, where you can transfer money from your account to someone else without having to use a credit card or something else.

Dobbins notes that Georgia United Credit Union uses a third-party for this service, though she didn’t clarify exactly who the third-party was, despite me asking. As such, it’s unclear if this was the credit union’s decision or the third-party’s.
